Insurers have incurred significant water ingress losses as a result of premature building envelope failure for buildings constructed in the 1985 to 1995 time frame. The challenge that faced Willis and their insurers in the development of their warranty program was the implementation of an underwriting methodology to accurately assess and monitor projects to ensure low risk. In 1998, Willis and their insurers contracted RDH to help them develop this risk assessment methodology. The confidence that Willis and their insurers have in the risk assessment process has allowed them to offer 10-year water penetration warranty coverage, the first program in the industry to do so.
